Report with page items

Hello all,
I am using APEX 4.0.3 and I would like to create a report where I could have editable page items within it. My objective was having for instance a variable number with its characteristics displayed in the report and the in one column be able to choose one second from a select list to associate to the first one.
In resume I need to have both a select list in the report, and I need to know how do I access the value of this item in each of this rows.
Thank you,
Mike

You need to loop.
Check out "Referencing Arrays,Referencing Values Within an On Submit Process" sections in following documentation.
This should give you fair idea.
http://download.oracle.com/docs/cd/E10513_01/doc/apirefs.310/e12855/apex_app.htm
For example if you have report with following query
SELECT APEX_ITEM.TEXT(1,column_name) FROM myTable;
and if you have 10 rows in table, then 10 text items will display on your page.
Since we have given the ID (p_idx) as 1, we can refer these text items using G_F01 global array. (If its 2 then G_F02 etc. we can have upto 50 dynamic item on one page)
G_F01.COUNT gives us "number of items"
G_F01(i) gives us value of i ^th^ text item value.
Hope it helps
Regards,
Hari

Discoverer Viewer Report with Page Items Slow Performance

I created a report in Discoverer User that has page items and parameters and runs fine (under 3 minutes) in Discoverer User, but when I try and run it in Discoverer Viewer it takes a long time. It took over 70 minutes before manually terminating it. I made a copy of the report and removed the page items and tried to run it again in Discoverer Viewer and now the report runs in under 3 minutes. Any idea why a report with page items would run in Discoverer user fine, but not discoverer viewer?
I am using Oracle Business Intelligence Plus 10g (10.1.2.55.26)

As long as you can access the middle-tier server where Discoverer Viewer is running, you should be able to run and view Discoverer worksheets.
While it is difficult to even start guessing what the problem might be, if the machine you installed Discoverer on has DHCP addressing, you will run into problems.
Thanks

REPORT WITH CHANGING ITEM ON THE SAME COLUMN

Hi to all,
i'm trying to build a report with different item in the same column.
Is that possible in any way using other Oracle technique?
i'm not doing anything specific here, only i would like to know if the following possibility exist or not and how can i let apex render the htmldb_item fields 'dynamically'.
Using this CODE inside a PL/SQL function body returning sql query I obtain the following report content. Such the code of htmldb_item.fields is written, as a field value the HTML_ITEM is not rendered, so only the description of them appear in the report.
Does somebody know some tricks to make it work?
Thanx a lot
1     2     LAST_CALL     htmldb_item.date_popup (4, ROWNUM, FLD_VALUE,'dd/mon/yyyy') VALUE
21     1     AGE     htmldb_item.text(4,FLD_VALUE,10,10) VALUE
create or replace FUNCTION FNC_GEN_GUI_ITEM(ITEM_TYPE NUMBER) RETURN VARCHAR2 AS
STRHTMLDITEM VARCHAR2(4000);
BEGIN
CASE ITEM_TYPE
WHEN 1 THEN STRHTMLDITEM:=' htmldb_item.text(4,FLD_VALUE,10,10) VALUE ';
WHEN 2 THEN STRHTMLDITEM:=' htmldb_item.date_popup (4, ROWNUM, FLD_VALUE,''dd/mon/yyyy'') VALUE ';
END CASE;
RETURN STRHTMLDITEM;
END FNC_GEN_GUI_ITEM;
MY TABLE AS FOLLOWS:
CREATE TABLE "NEWPROJ"."DINFIELDGUI"
(     "ID" NUMBER NOT NULL ENABLE,
     "FLD_TYPE" NUMBER,
     "FLD_NAME" VARCHAR2(4000 BYTE),
     "FLD_VALUE" VARCHAR2(4000 BYTE),
     CONSTRAINT "DINFIELDGUI_PK" PRIMARY KEY ("ID"));

Hi to all,
i've solved, is very simple using decode inside the select:
SELECT
ID,
FK_HTMLDB_ITEM, DECODE(FK_HTMLDB_ITEM,1,HTMLDB_ITEM.DATE_POPUP(3,rownum,VAL,'dd-mon-yyyy'),2,HTMLDB_ITEM.TEXT(3,VAL)) VALORE
FROM TESTID
my table is:
CREATE TABLE "DEV"."TESTID"
(     "ID" NUMBER NOT NULL ENABLE,
     "FK_HTMLDB_ITEM" NUMBER,
     "VAL" VARCHAR2(4000 BYTE))
Bye Bye

Error (ORA-01403) saveing data form a report with apex_item items

Hi all,
I've a problem saveing data that's inserted into a report which I created using apex_item items. Reproducing the exact issue on apex.oracle.com will take me a lot of time, and I don't know if I really can reproduce this matter... So I hope I can explain my problem clearly enough, here...
The global story of the application is that its an application used for measureing objects. For these objects there are templates, with default properties. When measureing an object, the user must fill in those properties for the object. The report is build dynamicly, becouse each object has different properties and each property could be of an other kind (number, text, list, counter [=number field with add and substract buttons], and date). Depending on the type of the property, the report has to show an other item to fill.
The query for constructing this report is like this:
select defprop.proptyp_id,
apex_item.hidden(41,defprop.id) defprop_id,
defprop.nam,
decode(proptyp.id,
 1, apex_item.text(p_idx=>42,p_value=>''||
 decode(defprop.srt, 'CONSTANT', (select WRD
 from measurement_prop
 where defprop_ID = defprop.id
 AND measurement_id IN
 (SELECT ID
 FROM measurement
 WHERE OBJ_ID = obj.id
 AND DAT IN
 (SELECT latest_date
 from object_instance
 WHERE ID = obj.id)))
 ||'' ,p_attributes=>'class=case5_num'),
 2, apex_item.text(p_idx=>42,p_value=>''||
 decode(defprop.srt, 'CONSTANT', (select WRD
 from measurement_prop
 where defprop_ID = defprop.id
 AND measurement_id IN
 (SELECT ID
 FROM measurement
 WHERE OBJ_ID = obj.id
 AND DAT IN
 (SELECT latest_date
 from object_instance
 WHERE ID = obj.id)))
 ||''),
 3, apex_item.select_list_from_query(p_idx=>42,p_value=>''||
 decode(defprop.srt, 'CONSTANT', (select WRD
 from measurement_prop
 where defprop_ID = defprop.id
 AND measurement_id IN
 (SELECT ID
 FROM measurement
 WHERE OBJ_ID = obj.id
 AND DAT IN
 (SELECT latest_date
 from object_instance
 WHERE ID = obj.id)))
 ||'', p_query=> 'select wrd, id from property_typewrd where proptyp_id = ' || proptyp.id ||' order by vlgnum', p_show_null=> 'NO'),
 4, apex_item.text(p_idx=>42,p_value=>''||
 decode(defprop.srt, 'CONSTANT', (select WRD
 from measurement_prop
 where defprop_ID = defprop.id
 AND measurement_id IN
 (SELECT ID
 FROM measurement
 WHERE OBJ_ID = obj.id
 AND DAT IN
 (SELECT latest_date
 from object_instance
 WHERE ID = obj.id)))
 ||'',p_attributes=>'class=case5_num')
 || '<a name="add_f02" href="#"><img alt="add" src="#WORKSPACE_IMAGES#plusBig.gif"/></a> '
 || '<a name="sub_f02" href="#"><img alt="sub" src="#WORKSPACE_IMAGES#minusBig.gif"/></a>',
 5, apex_item.date_popup(p_idx=>42, p_value=>''||
 decode(defprop.srt, 'CONSTANT', (select WRD
 from measurement_prop
 where defprop_ID = defprop.id
 AND measurement_id IN
 (SELECT ID
 FROM measurement
 WHERE OBJ_ID = obj.id
 AND DAT IN
 (SELECT latest_date
 from object_instance
 WHERE ID = obj.id)))
 ||''),
 oms
 ) waarde
from default_property defprop,
object_instance obj,
property_type proptyp
where defprop.stdobjver_id = obj.stdobjver_id
and defprop.proptyp_id = proptyp.id
and obj.id = :P2200_ID_INVThis report works fine. Depending on the type of the property it shows a numberic field, text field, selectlist (with right values), counter field or date field.
If the default property is set to a 'CONSTANT' value, the last known value is filled in.
With a javascript I check the numberic field value and achieve the counterfield to add or substract values when 'plus' or 'minus' is clicked.
This javascript is placed in the field 'Execute when Page Loads' in the page properties in APEX. Here is the code:
/*Execute when page loads*/
/*Allow only numbers */
number_elem = $('input[name=f42].case5_num');
number_elem.keypress(function(event) {
if (event.which && (event.which < 46 || event.which > 57 || event.which == 47) && event.keyCode != 8) {
 event.preventDefault();
if (event.which == 46 && $(this).val().indexOf('.') != -1) {
 event.preventDefault();
//for mouse events, remove any non numeric characters
number_elem.bind('mouseup mousedown mouseleave', function(event) {
 this.value = this.value.replace(/[^0-9]/g, '');
/* Subtract Button */
$('a[name="sub_f42"]').click( function() {
number_elem = $(this).siblings('input[name=f42].case5_num');
currVal = number_elem.val();
if ( isNaN( currVal) ){
 elemVal = 0;
else {
 elemVal = Number(currVal);
if (elemVal > 0)
 number_elem.val(elemVal-1);
else
{ elemVal = 0; }
/* Add Button */
$('a[name="add_f02"]').click( function() {
number_elem = $(this).siblings('input[name=f42].case5_num');
currVal = number_elem.val();
if ( isNaN( currVal) ){
 elemVal = 0;
else {
 elemVal = Number(currVal);
number_elem.val(elemVal+1);
});Those two codes makes my report works fine. So far I'm happy. But now I want the data, which the user fills in the items, to be saved.
So I created a process that should do this for me (it wil run after the user hits a button), here is the code:
declare
 v_objmet_id number := 0;
begin
 select measurment_seq.nextval
 into v_objmet_id
 from dual;
 insert into measurment
 ( id
 , obj_id
 , dat
 values
 ( v_objmet_id
 , :P2200_ID_INV
 , :P2200_METDAT_INV
 /*Loop trough the values (g_f42 holds the value of the property)*/
 for i in 1 .. apex_application.g_f42.count loop
 /*g_f41 holds the key to the default property*/
 if apex_application.g_f41(i) is not null and
 apex_application.g_f41(i) > 0 then
 insert into measurment_prop
 ( measrument_id
 , defprop_id
 , wrd)
 values
 ( v_objmet_id
 , apex_application.g_f41(i)
 , apex_application.g_f42(i)
 end if;
 end loop;
end;After running this process, the application branches back to the page, clearing the cache and set some items I use for filtering an other report with their own values.
Both the process and the branche have a 'when button pressed' condition, where the same button is filled in. The branche fires on submit: after processing.
When I hit the button to save the data, I get an error: ORA-01403: no data found
In the debug info I can find there is encountered an unhandeled exception in the process, but I don't know what's going wrong...
I thought it could be something with the date field, I want to save, so I put it in a to_date() with the right format, but I still got the error...
I've also checked if the query which fetches the nextval of the sequence is correct, and it is, no typeing error in the sequence name, or something.
I'm using APEX 4.0.2
Edited by: Mir on 28-jun-2011 10:25
Changed some code of the javascript, it directed to the wrong item ID, now its correct

My problem is solved. The error occured when application item g_f41 was accessed, so my application couldn't find the data, the user putted in there. I now pasted this part of the sql, to the other apex_item field, so it became one field and now it works correctly:
select [...]
apex_item.hidden(41,defprop.id) ||
decode(proptyp.id,
 1, apex_item.text(p_idx=>42,p_value=>''||
 decode(defprop.srt, 'CONSTANT', (select WRD
 from measurement_prop
 where defprop_ID = defprop.id
 AND measurement_id IN
 (SELECT ID
 FROM measurement
 WHERE OBJ_ID = obj.id
 AND DAT IN
 (SELECT latest_date
 from object_instance
 WHERE ID = obj.id)))
[... etc ...]

Very intermittent missing page regions / report rows / page item values

My goals in making this posting are twofold:
1. I'm looking to see if anyone else has experienced this type of issue before.
2. I'm looking for ideas about what can be done to debug such an infrequent bug with serious implications.
Synopsis
I'm having a weird problem where very infrequently I will load a page and I'll notice that one or more page regions, report rows, or page item values are missing. If I reload the page the missing parts appear as they normally should.
By "very infrequently" I would say it happens to me somewhere between 1 in 100 and 1 in 1000 page loads, of course at my last project demonstration in happened twice in 10 minutes to my demo participants. I've attempted to debug this, but most of the techniques I know of involve reloading the page or reposting the form data and (of course) everything looks fine then.
Environment
* This has happened on multiple different pages, under ApEx 3.1 (Linux) and 3.2 (Solaris).
* I believe that so far I've only ever seen this under Firefox 3/3.5 under OSX, but since I do the vast majority of my development with this browser it's not reasonable to conclude that it only happens under Firefox.
Logs
* No application errors during this timeframe.
* Nothing of significance in the database alerts log (just thread notes and log sequences).
* Nothing of significance in the webserver log (just the usual mod_ossl connection errors).
Thanks for your attention,
Jason
Edited by: Jason G on Jul 24, 2009 12:43 PM

Well, thanks for reading the post anyway.
While working through some debugging steps I realized that I was populating some of the regions as the page rendered using AJAX -- this would pause the page rendering until the AJAX request returned. I believe that a hanging AJAX call was the likely culprit of the very intermittent symptoms I was seeing.
I moved the AJAX calls to the last region of the page and added a javascript function that "watches the page load" by checking for regions by ID and looking at javascript boolean flags to let me know when the page is fully rendered. If this process takes longer than 5 seconds it notifies the user that something happened and offers to reload the page for them in an effort to fix the issue.
So far, so good -- but it will take a lot of testing to convince me that this case is solved. I hope my documenting this is helpful for others in similar situations.
Good luck,
Jason

Refresh SQL Report (Submit Page Item)

I want to add a search field in a SQL Report. I have something like this
SELECT * FROM emp
WHERE emp_no LIKE :P1_SEARCH || '%'I want to do the search asynchronous, on keypress. The problem is that a SQL Report doesn't have a "Submit Items:" atribute like a interactive report.
So after i refresh the report:
$a_report($x('P1_REPORT_ID').value,'1','10','100');The report is refreshing (the circle icon on top of the screen) but nothing changes cause the :P1_SEARCH doesn't submits.
How could i submit a page item from JS ?
King Regards,
Cearnau Dan
PS: I'm using APEX 4 and using dynamic actions it's the same like the Javascript call.(still doesn't submits the :P1_SEARCH item)

Hi Dan,
I would suggest not to use the undocumented
$a_report($x('P1_REPORT_ID').value,'1','10','100');It's very likely that it will be changed in APEX 4.1
Dan.Cearnau wrote:

Numeric Dimensions with Page Items

If you have a numeric dimension such as a period number when you select the Page Item 'ALL' and it aggregates the rows it also aggregates any numeric dimension. Can you stop this other than changing the numeric dimension to a character object. ( this effects the sort sequence)

You need to loop.
Check out "Referencing Arrays,Referencing Values Within an On Submit Process" sections in following documentation.
This should give you fair idea.
http://download.oracle.com/docs/cd/E10513_01/doc/apirefs.310/e12855/apex_app.htm
For example if you have report with following query
SELECT APEX_ITEM.TEXT(1,column_name) FROM myTable;
and if you have 10 rows in table, then 10 text items will display on your page.
Since we have given the ID (p_idx) as 1, we can refer these text items using G_F01 global array. (If its 2 then G_F02 etc. we can have upto 50 dynamic item on one page)
G_F01.COUNT gives us "number of items"
G_F01(i) gives us value of i ^th^ text item value.
Hope it helps

Hari

BUG?: Paginate Doesn't Work with Page Item with Source as Database Column

However, if you first submit the page, then paginate, it works as expected.
Reproduced:
http://apex.oracle.com/pls/apex/f?p=54920:57:106342795192226::::P57_ID:1
If I for e.g. use an item with static assignment, it works fine.
Cheers,
Trent
Edited by: trent on Apr 19, 2013 11:59 AM
Also, it works fine when you reference the PK column.

Just like with the paginate, the problem may also happens when you change the sort column or direction by clicking on the header.
If the item in the WHERE clause was being set fromt he URL this wouldn't be an issue because it would be saved on the Persisten Session state.
Regarding session state, there are two kinds Temporary or in memory and Persistent. When the page is rendering the item values are only on the Temporary session state. This is why the report renders correctly on page load.
The item value won't go to Persistent session state until the page is submitted. Item values also go to Persistent session when they are passed in the URL, or explicitly set with a computation, etc..
The Session state Dialog can only show the Persisten session state which is saved in DB tables. It's unable to show you the values during page render. For that you need other mechanisms like debug messages.
I think that when you set page item as SQL query and Only when current value session state is null the value must be saved to Persistent session state. If you can examine the value with the Session Dialog then that would confirm that.
Hope this helps.
Thanks

Problem with using sql with page items

Hi
I have a simple query that when i enter this works
SELECT SUGGESTION_ID, SUPERVISOR_ID, OVERVIEW
FROM PROJECT_SUGGESTION
WHERE SUPERVISOR_ID = 1;
But when i enter this doesnt
SELECT SUGGESTION_ID, SUPERVISOR_ID, OVERVIEW
FROM PROJECT_SUGGESTION
WHERE SUPERVISOR_ID = &P12_SUPERVISOR_ID;
Even though the value of the page item supervisor_id for page 12 is 1.
Anyone know why this is or another way i can refrence the page item?
thanks
Dan

Instead of &P12_SUPERVISOR_ID
try
:P12_SUPERVISOR_ID
And i think when you used the & you follow it with a period. ie. &P12_SUPERVISOR_ID.
Just a guess.

Just discovered I need a reference tool for research reports with pages...

I love the great tutorial that tells you to insert a function that does not come standard with pages. One would really think a bibliography tool or simple endnote feature would be pretty basic for a word processor.
So.....EndNote is the featured program on the tutorial....though I don't believe it is made by Apple (?).
Q: Are there other options for a program that will do research report-level citations in Pages? Or do I have to now spend 2x what I paid for the entire iWorks suite for this simple luxury?

Call print apex_util.get_print_document() with page item values

Hi all
I ran into an issue that very frustrated as it sounds so simple.
I'm in Apex 3.1.
My database has table TAB_CLASSES, TAB_STUDENT
My application has page 1 with P1_SID is student_ID
I had an simple report query name Class_query, show all classes that a student attends
select * from TAB_CLASSES where SID = :P1_SID;
I also select option "include application and session information"
I had report template Class_template
In my application, I have a process tried to generate report list classes for all students.
l_report blob;
for x in (select * from TAB_STUDENT)
loop
:P1_SID := x.SID;
l_report := apex_util.get_print_document (
p_application_id => :APP_ID,
p_report_query_name => 'Class_query',
p_report_layout_name => 'Class_template',
p_report_layout_type => 'rtf',
p_document_format => 'pdf'
insert all the l_report into database with SID as a part of l_report name (*)
end loop;
After this, I got multiple of l_report blob in database, number of report is exactly number of student in the TAB_STUDENT table. The problem is that every report looks the same, and it got the information of only first student
I guessed it did not pass the item value (P1_SID) every time it call the get_print_document, but it still shows in the report name (*)
Please help me. Thanks for any idea.

Problem with Page-Item

Description:
I created a database link with our Production-Database to publish some data
via Intranet.
Some pages got links to open Popup-Windows for a detailed description of the
data. Every page was built in the same way - a list with data and the ID got a link like this:
#ID#
In this case I created a link to open page 2 in a different window. On page 2 I use &P2_ID. as title and use :P2_ID for my sql-statement.
Problem:
On my popup-page 104 I see my title &104_ID. but my sql-statement returns nothing. The sql-statement itself works if I change :P104_ID to the value I can see in my title.
So I have really no idea why I can see the value of P104_ID if I use &P104_ID. or if I change the hidden item P104_ID to a textbox and if I use it in my SQL-Statement as :P104_ID I'll get no result. All other pages work fine.
Any idea?
Dietmar

Hi! 
This one should be my list I link from to page 104. The first row is my ID I store in P104_ID: 
 
AV8B 
C-160 
C130H 
E3A 
 
My link again: 
<href="javascript:popupURL('f?p=&APP_ID.:104:&APP_SESSION.::::P104_ID:#AC_ID#')">#AC_ID#</>
 Remark: I did'n forget the A in front of HREF! 
My Page 104 looks like the other pages I did it in the same way: 
Page-Title: &P104_ID. 
It shows allways my data "AV8B" or "C-160" or "C130H" etc. 
My SQL-Statement looks as follows: 
select UNIT_NAME 
from AIR_UNIT@BLUE 
where AC_ID = :P104_ID 
I can not understand why I can see in my title "AV8B" and the result of any SQL-Statement is the same: no data found! 
If I replace in SQL :P104_ID with AV8B I get my result list. The obove statement was just a simple test script but doesn't work even if I use: 
select AIR_UNIT.UNIT_NAME 
from AIR_UNIT@BLUE 
where AIR_UNIT.AC_ID = :P104_ID 
or using instead of the unit_name ac_id doesn't work either! 
I've got really no idea!

Can somebody please help-..with page ITEM

Can somebody please help…..
I have an Item named P11_FLAG on Page 11 of my application. I want to reference or access the value of this Item in all the pages of my application. I have tried several options but it seems not to work. I will really appreciate your help on this regard.
Thank you

referencing from other pages in code, use :P11_FLAG or external packages you can use the function v('P11_FLAG') or in substitution situations like referring to it in a report title &P11_FLAG. (note the last full stop).
